BED.

To all whom it may concern:

Be it known that we, WILLIAM A. DAVIS and ALBERT GREENWOOD, citizens ofthe United States, residing at Knoxville, 'in the county of Knox, 'Stateof Tennessee, have invented a new -and useful Bed, of which thefollowing is a specification.

The device forming the subject matter of this application isa bed andone object of the present invention is to provide novel means forcooling, ventilating and disinfecting the bed.

The invention is applicable to operating tables, couches, school desks,and the like and the term bed is to be construed as meaning anystructure upon which a person may wish to recline or sit for any purposewhatsoever.

It is within the scope of the invention to improve generally and toenhance the util-' ity of devices of that type to which the presentinvention appertains.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the.

details of construction hereinafter described and claimed, it beingunderstood that changes in the precise embodiment of the inventionherein disclosed can be made with in the scope of what is claimed,without departing from the spirit of the invention.

The invention is disclosed in a single perspective figure.

, carrying 'out the invention there is provided a. suitable support 1of. any desired form, upholding a box-like casing 2.

Secured to one end of the casing 2 and communicating with the interiorof the easing is a flexible tube or pipe 3-which may be of any desiredlength, the same communicating with a pump 4 which if desired, .may bemounted upon wheels 5 for the sake of portability, the outlet of thepump being indicated at 6 and the numeral 7 denoting any. suitable meansfor actuating the pump. he pump, preferably, is of the combined suctionand blower variety, so that at the will of the operator, air may bewithdrawn from the casing? or be forced thereinto.

Fixed to and upstanding from the longitudinal edges of-the casing 2 aredeflectors 8 including horizontally dis osed wings 9 extended toward thelongitu 'nal center of the casi g 1.

Supported on the casing '2 is a rest or Specification of LettcrsPatent'Application filed July 25, 1914.

.what is claimed is mattress;

Patented June 15 1915. Serial No. 853,083.

' mattress 10 the word mattress being construed to mean a suitablestructure of any sort upon which a person may recline, lean,

sit or otherwise rest. The mattress ,10 is somewhat narrower thanthecasing 2 so that spaces 11 exist between the edges of the mattress 10and the deflectors 8. Between the deflectors 8 and the adjacent edges ofthe mattress 10, the upper wall of the casing 2 is perforated as shownat 12.

In practical operation, through the medium of the pump 4, a suction maybe created within the casing 2. Air will then be drawn from above themattress 10, beneath the wings 9 of the deflectors 8 and between thedeflectors and the adjacent vertical edges of the mattress, the airpassing through the perforations 12 into the casing 2 and'out' of thecasing by way of the pipe 3. Thusit will be obvious that objectionableodors may be removed, the air being discharged through the outlet 6 ofthe pump, it being possible to sterilize or disinfect the air and thusdeliver-the air outside of the building in which the structure hereindescribed is located. The device tends to create a draft of greater orless strength across the top of themattress 10, thus promotingventilation and aiding in regulating the temperature. The structure isadapted to be'used not only upon sleeping beds but upon operatingtables, school desks, and in other places where comfort and health notonly of the person reclining upon the bed or table, but

of the attending physician or nurse, as well,

are to be considered.

Instead of sucking the an around the mattress or in. addition thereto,the mat- I tress may be perforated.

Obviously a number of structures such as herein described can beconnected to a central suction plant.

If desired a suitable covering of rubber or other like material could beplaced over the bed so as to direct medicated air to the I occupantthereof.

Having thus described the 1. In a device of the class described, .a.perforated conduits disposed along the edges of the mattress; deflectorsoverhanging the perforations; and means for sucking air through theperforations of all of the conduits at once.

'2.'In a device of the class described, a casing having sets ofperforations; a matinvention,

of perforations; deflectors located outwardly of the perforations; andmeans for forcing air through the perforations to ventilate the surfaceof the mattress.

3. In a device of easing having sets of perforations; deflectors securedto the casing and overhanging v meansfor forcing air t1ons of thecasing.

the perforatlons; a mattress on the casin and extended beneaththe-deflectors; an

through theperfora- 4. In a device of the class described, a box-likecasing provided along its edges the class described, a

essrs with upright deflectors and adapted to receive a mattress betweenthe deflectors, the casing being perforated adjacent the deflectors; asuction pump; and a connection between the pumgfland the casing.

In testimony t t we claim the foregoing as. our own, we have heretoafiixed our signatures in the presence of two witnesses.
